MOTOR-SUPPORT FOR PRINTING-PRESSES.

Patented Nov. 2, A1920.

Application filed January 31, 1918. Serial No. 214,761.

To all 'whom t may concern Be it known 'that I, FRED S. ENGLISH, a citizen of the lUnited States, and a resident of New. London, county of New London, and State of Connecticut, have invent.- ed certain new and useful Improvements in Motor- Supports for Printing Presses, of which the following is a specification.

My invention relates to a. motor base or support for printing presses. The 'object of theinvention is toprovide a very simple and rigid support which may be attached to the frame of any printing press to form a base or support on which the motor for driving the press is mounted. The base is so constructed that it may be adapted to any standard motor, the ob'ect here being to provide members to whic thevbase 0r legs of the motor frame may` be bolted by utilizing the same means of attachment as where a motor is attached to a solid structuresuch as a floor. Provision is made for adjusting the position of the motor laterally of the press frame-toaline its pulley with the'main pulley of the printing press and for adjusting the position of the motor lengthwise of the press to tighten the driv ing belt through which'the power is trans mitted from the motor pulley to the pulley of the press.

The device has a long and very rigid bearing or connection with the press frame so that 4there will be no displacement vof the motor even after long usage. Very simple and eiicient devices are provided for securing the lateral adjustment ofthe motor and for keeping its shaft parallel with the shaft o f the printing press during this lateral adjustment. The member which is primarily attached to the pressv frame may be rigidly and unalterably attached thereto and the `adjustments may be made without altering the position of said member. There is thus a rigid support for the motor not only when it is finally arranged for operation but while the motor is being adjusted in position. Y

In the drawings forming part of the application,

y Figure 1 -is a side elevation of part of a printing press, showing my invention applied thereto,

Fig. 2 is an end elevation of part of the press frame and ,showing the motor base in vside elevation,

modified construction which is preferable for a long motor. f

In lthe drawings I have shown part of the side frame v1 of a fiat bed reciprocating printing press. The pulley 2 on the shaft 3 is adapted to be operated by the motor to v drive the impression cylinder 4 throughV4 the small gear 5, the main gear 6 and the intermediate gear 7, this .being a standard form of ldrive for presses of this type. It. is to be understood that the present invention is adapted to be applied to any other form of press.

The present invention relates to the means for supporting the motor for driving the pulleyQ, In Figs. 1 to 4 the member which is secured in fixed relation to the press frame 1 consists vof a bracket 8 having a vertical web' 9 which is fastened against` the outer surface of the press frame by the bolts 10, and of a horizontal web .11. The bracket .is of considerable length, preferably longer than the base of the motor which it is to support, in order'to provide a substantial support which will not be twisted or in any way moved by vibration during the operation by the motor. The bracket when once fixed to the frame requires no adjustment and it forms a fixed support. for the motor even when the latterjis being adjusted to aline the pulleys or to'take up slack in the driving belt.

The horizontal web 11 of the bracket is provided with parallel T slots 12 extending lengthwise ofthe bracket and lengthwise in relation to the press. There are parallel rails 13 which rest on and are adapted to slide over the horizontal web 11 of the fixed bracket and these rails are intended to slide lengthwise of the bracket and press. vFlach rail has extensions 14 front yand back through which pass bolts 15 the heads of whichtravel in the T slots 12 of the bracket web 11.l These bolts-are provided with nuts 16 at the top, by means of which the bolts are tightened to secure the rails in fixed relengthwise of the bracket when they are loosened and that they are prevented from moving upwardly by the heads which lie'in the cross sections of the T slots.

Each rail 13 is providedwith a T slot 17 similar to the slots in the bracket, but these slots 17, extend lengthwise of these rails which is crosswise in relation to both the bracket and the press frame, or at right 'angle to the slots 12. The motor 18 shown herein by way of example has a base including four feet 19 on which the motor is adapted to rest and these feet are placed on the rails 13, two on each rail. Tt will be understood that the rails are adjusted along the bracket so that they will aline with the feet of the motor. There are bolts 2O passing through the feet 19 of the motor and engaging in the 'l' slots 17 of the rails 13, suitable nuts 21 being provided for tightening these bolts to secure the motor to the rails.

There is a block 22 adjusted along the bracket web 11 and it has a bolt 23 which engages in one of the 'l' slots 12 ot the bracket in the same manner as the bolts 15. By means of the bolt 23 the block 22 may be secured at any position along the-bracket to bring the block near one of the feet of the motor. This block has an adjusting screw 24 which acts against one 'of the rails 13.

In setting ,up the device suitable holes are drilled in. the press frame to receive the bolts 10.l The bracket 8 is then placed against'the frame and secured in place by these bolts.

The -rails 13 and their bolts are then arranged upon the bracket 8, being spaced to agree with the distance between the feet-of the motor. The motor is then placed with its feet resting onl the rails 13 its bolts 2O being lalso connected in place. Be- :fore tightening the bolts 20 the motor will be moved along the rails 13 and laterally of the, press until the pulley 25 on the motor shaft 26 alines with the pulley 2 of the press, so that the belt 27 will be alined on these pulleys. When this adjustment has been made the bolts 20 are tightened to fix the position of the motorV transversely of the press.

The motor and the rails will then be moved lengthwise of the bracket l8 toward or from the pulley 2 to approximately the position necessary to take up the slack in the belt. The block 22 is then adjusted along the bracket to bring it near one of the rails 13, and its bolt 23-is then tightened. The screw 24 is then turned and it acts against the adjacent rail to force the rails and motor along the bracket 8 until the slack in the belt 27 has been taken up and then the several bolts 15 are tightened. vThe device is now ready for use. It will be noted that the bracket 8 when once secured in place requires no adjustment and it forms a solid support for the motor while the latter is being adjusted laterally and longitudinally of the press and this makes it possible to set the motor quickly and with accuracy. The bracket 8 forms a very rigid support of suiiicient extent lengthwise of the press to prevent any twisting of the motor while in operation.

The device shown inv Figs. 1 to 4 is adapted to support a motor which is of such length that it will lie substantially outside of the press frame. In Fig. 5 l have shown a modification in the construction to adapt it to longer motors which may lie partly inside and partly outside the press frame. In this case the bracket consists of separate' halves 28 and 29 one secured tothe outside of the press -frame and the` other to the 'inside thereof, the'bolts 10 securing both bracket members in place. The only otherdifference in this construction is that each bracket section has a T slot 12 and the' bolts 15 of the rails engage with and move along these in the same way that the bolts move in the slots 12 of the first construction. All the adjustments are made the same as in the first construction. The purpose of the construction is to provide a bracket affording a wider support where the length of the motor makes this advisable.

Having described my invention what. l-

claim is:

A device of the class described comprising a bracket adapted to be secured to the fra-me of a printing press, said bracket having aD horizontal supporting portion eX- tending a substantial distance lengthwise o'f the press, said bracket having a T slot 'extending lengthwise of the press, separate rails resting on said bracket and extending laterally of the press, bolts engaging said T slot and adapted to secure said rails individually in different positions along said bracket, adjustable means 'for securing a motor on said rails in difi'erent positions laterally of the press, a block, and a bolt engaging said l' slot for securing said block in different positions along said bracket, and an adjusting screw in said block adapted to move said rails along said bracket for the purpose set forth.
